Fig. 1 shows an envelope or case 1 made of flexible black paper, provided with an exposing aperture whose edges are strengthened by a cardhoarr'l tition is metallic and comprises springs and cylindrical portions and the manufacture theneoi is thus complicated and expensive. As a rule the known film packs contain a dozen lilms. and the case containing the same cannot be used a second time after the said films have been exposed.

The combination of the said case and h a k 'n shape and ze, but is as yet inthe interchangeable wall will thus constitute l: is necessary to add thereto a a device which is adapted for use with the rral lort on which is provided with known cameras and holders in the same man ylinc portion for changing the her thelihn packs. films and with suitable springs whereby the The following description refers to the acsaid films may be brought into the plane of companying drawings which are given by exposure. The said central portion consists way oi? exampleand in which: of an in?erchangeable metallic plate 10, Fig. F 1 is a perspective view of an envelope 4; said. plate comprises a flat portion which is :i orming pa t of the device according to the applied against the back of the films in the invention.

rear of the exposing aperture a lower cylinframe 3. and with a slot l,

drical portion 11 cooperating with the angle of the folded case, and two springs 12 of steel wire between which is'disposed the rear portion of the said envelope or case.

The film-holding device which is thus constituted by the folded case and the plate 10 which is disposed in the folded portion, may be inserted, Fig. 5, into a suitable holder comprising the two parts 13 and 1d hinged to gether, the springs 12 bear upon the part 13 and apply the plate 10 against the part 1-1, which is thus brought into contact with the exposing aperture 2 of the case; the pressure of the springs is transmitted solely to thefilms to be exposed and without interfering with. the portion of the case employed for containing the exposed films.

In the known film packs, each film can be withdrawn after it has been exposed, for purposes of separate de"elopment, but in this event a part of the box must be opened-which is a diificult and complicated matterand must then be closed by pasting, which is difficult to carry out in the proper conditions in the dark.

In the device according to the present invention, the films can be removed at will with great facility, for this purpose. through an opening 21 in the rear face of the case 1-seen in elevation in Fig. 6is passed a strip 15 which is drawn upon in the direction of the arrow 7", it being secured to a fiat ring 16 of cardboard or tin plate surrounding the black paper traction bands 8 which are out less width than the films. An unexposed film occupies a position such'as that of the film 17, whilst a film withdrawn after exposure is brought to the position of the film 18; in this position. the shoulder 19 of the black paper is in contact with the ring 16. v

'V/hen the strip 15 is drawn in the direction of the arrow f, the ring 16 will draw out all the films occupying the position oil the film 18, i. e. all the exposed films, and these will move to a point about midway in the aper turo 2, 7. The ring 15 will have no action upon the unexposed films such as 17.

The films which are brought intotheposition of the film 20, Fig. 7, can be readily re moved through the aperture 2 without any removal of the outer envelope. After this operation, it will be unnecessary to bring back the strip 15, for the latter will be drawn back by the shoulder 19 of the first film withdrawn during the succeeding operation.

Among other advantages, and in addition to the reduced cost of construction, the film case according to the invention will have the minimum thickness before as well as after the exposure oi the films, since theinterchangeable metallic plate is utilized only when the case is disposed in the holder. vVhen apart from the holder, the said film pack is in reality only a folded case or envelope containing a certain number ofsheets-of paper and films.

Obviously, the constructional arrangements hereinbefore set forth are given solely by way of example and for the proper comprehension oi the invention, and are in no wise of a liinitative nature.

Having now described my invention, what I claim as new and desire to secure by Letters Patent is:
